Premium UL 3573 Silicone Ignition Wire (10KV, 200°C)
Engineered for the most demanding thermal and electrical environments, the CableApex UL 3573 wire is a high-performance ignition cable designed for industrial and commercial heating systems. Compliant with the rigorous UL 758 standard, this wire provides unparalleled reliability for high-voltage spark ignition applications where standard PVC or XLPE wires would fail.
Advanced Material Construction
The core strength of the UL 3573 lead wire lies in its dual-layer composite protection, specifically designed to withstand both electrical arcing and physical abrasion during installation and operation:
- Primary Insulation (Silicone Rubber): Extruded with a minimum average thickness of 30 mils of premium SR-Silicone. This layer delivers exceptional dielectric strength, preventing high-voltage breakdowns up to 10,000 Vac, while maintaining flexibility at continuous operating temperatures of 200°C.
- Outer Protective Armor (Fiberglass Braid): To combat mechanical wear and tear, the silicone core is tightly wrapped in a durable fiberglass braid (or serve). An additional ultra-thin insulation layer (10 mils minimum) is applied over the braid, ensuring the wire resists fraying and chemical exposure in harsh appliance environments.
